Lenovo mouse won't move when typing?

I can't play games like minecraft because i can't look around because of this problem. Any way to help?
i have windows 8 btw

Added (1). i have a laptop, so i guess its a touchpad, not a mouse

Install the latest mouse drivers from Lenovo.

Assuming it's a USB mouse, try moving it to another mouse port. I have a similar problem with a webcam the stops working from time to time and I just move it to a different port.

There should be a trackpad icon in the tray on the taskbar next to the clock. Give that a right click or double click on it to open the trackpad properties. There should be an option in there called palm check or something similar. Turn off or turn down the sensitivity as far down as it'll go.
